The attack allows a malicious user to physically login on a target host in a Kerberos-based network, under the assumption that he knows a valid user principal and has the ability to manipulate network traffic. Our research shows that all recent versions of the Microsoft Windows operating systems are vulnerable to the attack. AFFECTED SYSTEMS: Windows XP Service Pack 2 Windows Vista Service Pack 1 Windows 7 (using a Windows Server 2008 Domain Controller) INFO: More detailed info, with whitepaper and proof-of-concept code can be found at: http://secgroup.ext.dsi.unive.it/kerberos/
